Description

Es sind bereits Einrichtungen zur Unterdrückung der Nutharmonischen vorgeschlagen worden, die in der gleichzeitigen Anwendung der Schrägstellung der Polschuhkanten und der Bruchlochwicklung bestehen. Durch die Schrägstellung der Polschuhkanten wird die Feldverteilung, d. h. der magnetische Kraftfluß, beeinflußt und durch die Bruchlochwicklung der Wicklungsfaktor. Dieselbe Wirkung kann auch dadurch erzielt werden, daß die Bruchlochwicklung vereint angewendet wird mit einer Versetzung der Polschuhkanten an Stelle ihrer Schrägstellung oder mit einer Versetzung der Dämpf er st.äbe; letztere werden beispielsweise unsymmetrisch in den Pol schuhen angeordnet.Means for suppression of the nut harmonics have already been proposed been involved in the simultaneous application of the inclination of the pole piece edges and the broken hole winding exist. Due to the inclination of the pole shoe edges the field distribution, d. H. the magnetic flux, influenced and by the broken hole winding the winding factor. The same effect can also be achieved by using the broken hole winding in unison is with an offset of the pole shoe edges instead of their inclination or with a displacement of the damping he would st. the latter are, for example, asymmetrical in the Pole shoes arranged.

Unter den Bruchlochwicklungen gibt es solche, die die günstige Eigenschaft, die von den Nutharmonischen induzierten Spannungen zu einem von Null wenig verschiedenen Wert zu addieren, nur für ungeradzahlige Nutharmonische besitzen, dagegen sich für geradzahlige Harmonische ebenso ungünstig verhalten wie Ganzlochwicklungen für ungeradzahlige Harmonische. In diesem Falle wird gemäß der Erfindung dafür gesorgt, daß geradzahlige Harmonische nicht entstehen können. Dies wird dadurch erreicht, daß bei Bruchlochwicklungen 'mit ungünstigem Verhalten hinsichtlich der geradzahligen Nutharmonischen die in bekannter Weise gleichzeitig; angewendete Versetzung der Polschuhkanten oder Dämpferstäbe nach bekannten Regeln (vgl. E. u. M. vom 2. 5.1926, Heft 18, S. 325 ff.) nicht von Pol zu Pol, sondern polpaarweise erfolgt.Among the broken-hole windings there are those that have the favorable property that of the nut harmonics induced voltages to a value little different from zero to add only for odd-numbered nutharmonics, on the other hand, for even-numbered ones Harmonics behave just as unfavorably as whole-hole windings for odd-numbered ones Harmonics. In this case, according to the invention, it is ensured that even harmonics do not arise can. This is achieved in that with broken hole windings' with unfavorable behavior with regard to the even-numbered Nutharmonischen in a known way simultaneously; applied displacement of the pole shoe edges or damper rods according to known rules (see E. and M. dated May 2, 1926, issue 18, P. 325 ff.) Is not carried out from pole to pole, but in pairs of poles.

Die Abbildung zeigt ein Ausführungsbeispiel. Es sind vier aufeinanderfolgende Polpaare ab, c CL1, e f und g h gezeichnet. Die Polpaare c d und g h weisen eine Versetzung der Polschuhkanten auf, die durch die gestrichelten Linien angedeutet ist.The figure shows an exemplary embodiment. Four consecutive pole pairs ab, c CL 1 , ef and gh are drawn. The pole pairs cd and gh have an offset of the pole shoe edges, which is indicated by the dashed lines.
